5 1 Properties and Services 1 Properties and Services Application The IWLAN/PB Link PN IO is a gateway that connects the Industrial Wireless LAN (control level) and PROFIBUS (cell/field level) networks to each other. SCALANCE W78x The IWLAN/PB Link PN IO supports access to all PROFIBUS DP slaves on the subordinate PROFIBUS; DP slaves complying with PROFIBUS DP-V0 are supported and, as of firmware version V1.1.0, also DP slaves complying with the DP-V1 standard and Siemens DP slaves. The Industrial Wireless LAN (IWLAN) with RCoax and WLAN antenna for wireless or non-contact data transmission is ideal for a variety of mobile applications, including monorail conveyors and high-bay storage and retrieval systems. The IWLAN/PB Link PN IO can be operated in the following modes: Gateway as PROFINET IO proxy Gateway in standard operation BL2 5

6 1 Properties and Services Gateway as PROFINET IO proxy The IWLAN/PB Link PN IO is a key component of PROFINET IO. It is responsible for the connection between the PROFINET IO controllers on Industrial Ethernet and the PROFINET IO devices (DP slaves on PROFIBUS). From the point of view of the PROFINET IO controller on Industrial Ethernet, the process of accessing PROFINET IO devices that are connected to Industrial Ethernet via the Industrial Wireless LAN and IWLAN/PB Link PN IO and accessing PROFIBUS DP slaves that are connected to PROFIBUS DP is identical. IWLAN/PB Link PN IO acts as a proxy for the DP slaves connected to PROFIBUS DP. SCALANCE W78x Figure 1-1 Example of Using the IWLAN/PB Link PN IO PROFINET IO Proxy BL2 6

7 1 Properties and Services Gateway in standard operation The following services are available in standard operation: PG/OP communication PG/OP communication is used to download programs and configuration data, run test and diagnostic functions, as well as operate and monitor the plant (HMI systems). Assigning parameters to field devices (data record routing) You can use the IWLAN/PB Link PN IO as a router for data records that are addressed to field devices (DP slaves). In this way, devices that are not directly connected to PROFIBUS and, therefore, cannot access the field devices (DP slaves) directly, can transmit data records to the field devices via the IWLAN/PB Link PN IO. The SIMATIC PDM (Process Device Manager) is an example of a tool that creates data records for assigning parameters to field devices. Gateway to a DP master system with constant bus cycle time The IWLAN/PB Link PN IO acts as a gateway between the Industrial Wireless LAN and the field devices on a DP master system. The IWLAN/PB Link PN IO is used here as an active node along with a DP master on a PROFIBUS that has been set to constant bus cycle time. Cross-subnet S7 connections for HMI operation The IWLAN/PB Link PN IO forwards communication via S7 connections. This service is used for HMI applications (PC stations), for example. SCALANCE W78x Figure 1-2 Example of Using the IWLAN/PB Link PN IO in Standard Mode BL2 7

8 1 Properties and Services Gateway in mobile applications The IWLAN/PB Link PN IO enables wireless communication with programmable controllers in mobile applications, such as automated guided vehicle systems, high-bay storage and retrieval systems, and monorail conveyors. Solutions involving power rail boosters for PROFIBUS via slip contacts can, therefore, be replaced with a non-contact, non-wearing data transmission technology. It can be connected via a WLAN antenna or an antenna for use with an RCoax cable (leak-mode conductor). Industrial Ethernet Gateway in PROFINET IO applications with ipcf (industrial Point Coordination Function) IWLAN/PB Link PN IO supports ipcf mode. The use of ipcf is recommended particularly when a high throughput is required with large numbers of nodes or when very short handover times are necessary. The ipcf mechanism was further optimized for operation with PROFINET IO data traffic by handling PROFINET IO data traffic with high priority. BL2 8

9 1 Properties and Services Notice For PROFINET IO communication, we recommend that you always enable the ipcf mode. The signal strength must not drop below 60% or 65 dbm to ensure reliable operation. Please read the ipcf documentation in the operating instructions for SCALANCE W744-1PRO. BL2 9

10 1 Properties and Services Other properties and services Industrial wireless LAN IWLAN/PB Link PN IO provides a wireless interface (in compliance with IEEE b/g/a/h. Forwarding time messages (configurable option) The IWLAN/PB Link PN IO can forward time messages received by a real-time transmitter as follows: from Ethernet to PROFIBUS From PROFIBUS to Ethernet If there is a time master on Industrial Ethernet, the IWLAN/PB Link PN IO then receives time messages for time stamping diagnostic buffer entries and process signals. Option: C-PLUG as exchangeable medium for the project engineering data The IWLAN/PB Link PN IO allows the configuration data to be saved to a removable memory medium (C-PLUG). In this way, a defective module can simply be replaced by plugging the C-PLUG into the new module. Option: PRESET-PLUG The PRESET PLUG is a simple device for assigning a defined default setting to an IWLAN/PB Link PN IO and SCALANCE W devices. WLAN Security Properties Supported authentication standards: WPA, WPA-PSK, IEEE 802.1x, WPA2, WPA2-PSK Note: WPA2 (Wi-Fi Protected Access 2) includes the further development of WPA that implements the functions of the security standard IEEE i. Supported encryption methods: WEP, AES, TKIP Downloading firmware IWLAN/PB Link PN IO supports updating of the firmware (FW) using the firmware loader supplied with STEP 7 / NCM S7. A firmware update can be downloaded at any time from the PC/PG via the Ethernet port. Configuration You can configure the IWLAN/PB Link PN IO for all operating modes via Industrial Ethernet (recommended). If you use the device as a standard gateway, the configuration data can also be changed/supplied via PROFIBUS. BL2 10

12 3 Installation and Commissioning 3 Installation and Commissioning Use the overview below to find out which section is relevant to your application. PRESET PLUG is available (recommended procedure) PRESET PLUG is not available Installation and Parameter Assignment with PRESET PLUG > see Section 3.1 Installation and Parameter Assignment without PRESET PLUG > see Section 3.4 The device has been commissioned on the WLAN side and can be supplied with configuration data. Subsequent procedure depending on application Configuration with STEP 7 for use as a PROFINET IO device and gateway > See Section 4.1 Configuration with STEP 7 for use as gateway only > See Section 4.2 The device is ready BL2 12

13 3 Installation and Commissioning 3.1 Installation and Parameter Assignment with the PRESET PLUG The following section describes the recommended commissioning procedure with the PRESET PLUG up to the parameter assignment stage. If a PRESET PLUG is not used in your application, proceed as described in Section 3.4. The project engineering that is subsequently required is described in Chapter 4 Please read the additional notes in this section. At this stage, installation and configuration are carried out separately. Follow the steps below: Step Installation and Parameter Assignment with PRESET PLUG 1. Install the IWLAN/PB Link PN IO on a mounting rail. 2. Insert the PRESET PLUG into the C PLUG slot. The preset function of the PRESET PLUG only functions if the PRESET PLUG was configured beforehand for the IWLAN/PB Link PN IO. If the PRESET PLUG has not yet been configured, proceed as described in Section Connect the power supply to the IWLAN/PB Link PN IO (read the notes in Section 3.3). 4. Switch the power supply on. When the LEDs flash slowly, this indicates that the PRESET PLUG has been recognized. The LEDs for the PRESET PLUG function are explained in the device LED description; see Chapter 6 5. Press the reset button next to the C PLUG slot. The default settings for the PRESET PLUG are now copied to the device where they are stored. When the settings have been successfully copied, the LEDs stop flashing and switch to a steady light signal after a few seconds. 6. Now switch off the power supply and remove the PRESET PLUG. 7. Connect the IWLAN/PB Link PN IO to PROFIBUS and, via the antenna, to IWLAN. 8. Switch the power supply on. The device now runs with the parameters transferred by the PRESET PLUG and can be supplied with configuration data. The device is now commissioned on the WLAN side and can be supplied with configuration data. 9. Now continue with the configuration process depending on your application: Configuration with STEP 7 for use as a PROFINET IO device and gateway > see Section 4.2 Configuration with STEP 7 for use as a gateway only > see Section 4.1 BL2 13

14 3 Installation and Commissioning General notes IP parameters and device specific parameters are not changed Using the PRESET PLUG prevents duplicate IP addresses by ensuring that the IP parameters are retained unchanged. Other device specific parameters also remain unchanged, including: System Contact System Name System Location The WLAN interface is deactivated. The WLAN device interface is deactivated when the PRESET PLUG is inserted. The device cannot be operated with the WLAN when the PRESET PLUG is inserted. BL2 14

15 3 Installation and Commissioning 3.2 Configuring the PRESET PLUG Overview The PRESET PLUG is a simple device for assigning a defined default setting to an IWLAN/PB Link PN IO and SCALANCE W devices. The PRESET PLUG is first configured in a SCALANCE W788 with the required WLAN parameters and then inserted in the C PLUG slot on the target system for commissioning purposes. When several WLAN clients with the same parameters are used, the advantage of this procedure is that you do not have to assign parameters to each individual client manually. If a PRESET PLUG is not used in your application, proceed as described in Section 3.4. Notice The PRESET PLUG 6GK5798 8AB00 is only used for commissioning purposes. The device cannot be operated with the WLAN when the PRESET PLUG is inserted. Configuring the PRESET PLUG To configure a PRESET PLUG, you require a device of the type SCALANCE W7xx with a firmware version V3.0 or higher. You can use this procedure to configure a PRESET PLUG from scratch or to change an existing configuration. Follow the steps below: Step Procedure 1. Insert a new PRESET PLUG or one that has already been configured into the C PLUG slot on the SCALANCE W7xx, which must be switched off. 2. Switch the device on. 3. Open the Web interface for the SCALANCE W7xx. The Web interface displays the current settings for the PRESET PLUG (provided a configuration already exists). BL2 15

16 3 Installation and Commissioning Step Procedure 4. Set all the parameters as required for making the default settings for the target devices: This involves specifying whether the target device is to function as an AP or client. For the IWLAN/PB Link PN IO, choose Client. To ensure that the IWLAN/PB Link PN IO can later establish a connection with the AP correctly, adapt the following parameter settings to suit your specific application: System / Country Code SSID WLAN Mode Security ipcf Mode (if necessary) Other settings may also be required for your application (e.g. background scan channels). 5. When you have set all the parameters, open the System C PLUG menu and select the Create PRESET PLUG function. 6. Choose the target device type for which this PRESET PLUG is designed (in this case: IWLAN/PB Link PN IO). 7. To complete the configuration, select Modify. The PRESET PLUG has now been configured. 8. Switch the SCALANCE W7xx off and remove the PRESET PLUG. Note The PRESET PLUG you have just configured only functions with the device type you selected. BL2 16

17 3 Installation and Commissioning 3.3 Establishing the Connections Important Notes Notice Important notes on installation and operation: The module must be installed so that its upper and lower ventilation slits are not covered, allowing adequate ventilation. Note The PROFIBUS can be connected while the power supply is on. Notice The requirements of EN , surge immunity test on power supply lines, are met only when using a Blitzductor VT AD 24V type no Manufacturer: DEHN+SÖHNE GmbH+Co.KG Hans Dehn Str.1 Postfach 1640 D Neumarkt, Germany! Warning The IWLAN/PB Link PN IO product must be installed in an enclosure or switchgear cabinet. Where ATEX 100a (EN 50021) applies, this enclosure must meet at least IP54 in compliance with EN WARNING THE DEVICE MAY ONLY BE CONNECTED TO THE POWER SUPPLY OR DISCONNECTED FROM IT WHEN THE RISK OF EXPLOSION CAN BE EXCLUDED WITH CERTAINTY. Ground/chassis ground concept The device is grounded over the mounting rail. BL2 17

18 3 Installation and Commissioning Module accessories The accessories (including the power supply) required for connecting the IWLAN/PB Link PN IO to an Industrial Wireless LAN and PROFIBUS must be ordered separately. The optional C PLUG can also be ordered separately. For more detailed information and ordering data, refer to the Catalog IK PI PG/PC Connection You can connect the PG when configuring the CP as follows: Via Industrial Ethernet and WLAN interface (recommended) Via PROFIBUS (for standard operation only) Industrial Ethernet and WLAN interface (recommended) Commissioning the device for the WLAN is described in detail in this chapter (3). When configuring on the PG, a distinction must be made between the following modes: PROFINET IO use case In this use case, the IWLAN/PB Link PN IO obtains its project engineering data from the controller. This means: Controller and Link must be connected over the WLAN; The Link must already have been assigned a device name with STEP 7 so that the project engineering data can be downloaded. Read the detailed description of project engineering in Section 4.1. Standalone Mode In this use case, the IWLAN/PB Link PN IO is configured and downloaded as an S7 300 station. This can take place as soon as you have assigned an Ethernet address to the device with STEP 7. Read the detailed description of project engineering in Section 4.2. PROFIBUS (for standard operation only) The IWLAN/PB Link PN IO can be reached over the PROFIBUS interface. You must, however, first assign a PROFIBUS address in the project engineering. BL2 18

19 3 Installation and Commissioning Power Supply! Warning The IWLAN/PB Link PN IO is designed for operation with safety extra low voltage (SELV). This means that only safety extra low voltages (SELV) complying with IEC950/EN60950/ VDE0805 may be connected to the power supply terminals. The power supply unit to supply the IWLAN/PB Link PN IO must comply with NEC Class 2 (voltage range V, current requirement 300 ma). The device must only be supplied by a power supply unit that complies with the requirements of class 2 for power supply units of the National Electrical Code, Table 11 (b). If the power supply is installed redundantly (two separate power supplies), the total power of both power supplies together must meet these requirements. Exceptions: Supply by a SELV power source (complying with IEC 60950) or PELV power source (complying with VDE ) without restricted power is also permitted as long as suitable fire prevention measures are taken by means of: installation in cabinet or suitable enclosure installation in suitably equipped, closed room The power supply is connected over a 4 pin plug in terminal block. The power supply can be connected redundantly. The two inputs are isolated. There is no load sharing. When the supply is redundant, the power source with the higher output voltage supplies the IWLAN/PB Link PN IO alone. The power supply is connected to the housing over a high resistance to allow ungrounded installation. L1+: +24 V DC M: 24 V DC chassis L2+: +24 V DC M: 24 V DC chassis Figure 3-1 Power Supply BL2 19

20 3 Installation and Commissioning 3.4 Installation and Parameter Assignment without the PRESET PLUG Overview The PRESET PLUG is a simple device for assigning a defined default setting to an IWLAN/PB Link PN IO and SCALANCE W devices. If a PRESET PLUG is not used in your application, proceed as described below to assign parameters for the IWLAN/PB Link PN IO. Before carrying out the procedure described below, make sure that the device has the default settings as shipped. If this is not the case, use the RESET button to restore the factory settings (see Section 5.2.3) Configuration For the procedure described here, you need the following device configuration with an AP with parameter settings for the configuration (configuration AP): Configuration AP with SSID WLAN_CONFIG_AP Follow the steps below: Step Procedure 1. Install the IWLAN/PB Link PN IO on a mounting rail. 2. Connect the device to IWLAN via the antenna. 3. If necessary, adapt the AP settings to the default settings for the IWLAN/PB Link PN IO (see Section 5.1), so that it can be used as a configuration AP. BL2 20

21 3 Installation and Commissioning Step Procedure 4. Switch the power supply on. The device can now be accessed via its MAC address in the WLAN. 5. Use the PST (Primary Setup Tool) to assign the IP address and PROFIBUS parameters to the IWLAN/PB Link PN IO. Note: The PST (Primary Setup Tool) is on the CD supplied with the product and can be found in the following directory: 6. Log on to the IWLAN/PB Link PN IO via Telnet. To do so, open the MS DOS input prompt and enter the following command:telnet <IP address> Use the following default values to log in: Login: admin Password: admin 7. Set the parameters for the IWLAN/PB Link PN IO over the Command Line Interface (CLI) so that the device can be commissioned in the operational environment in which the configuration is also loaded. If necessary, adapt the Country Code in the first step and then make any further settings you require. If you modify parameters, you will be prompted to restart. You should, however, only restart when you have made all relevant settings. The device is now commissioned on the WLAN side and can be supplied with configuration data. 8. After completing the settings, commission the IWLAN/PB Link PN IO in its operative environment in the WLAN. 9. Now continue with the configuration process depending on your application: Configuration with STEP 7 for use as a PROFINET IO device and gateway > see Section 4.2 Configuration with STEP 7 for use as a gateway > see Section 4.1 Note For a detailed description of the commands of the Command Line Interface (CLI), see the operating instructions for the SCALANCE W744. These operating instructions (file name: MN_SCALANCE_W74X_0[76]) can be found on the CD supplied with the IWLAN/PB Link PN IO or on the Internet at the following address: BL2 21

22 3 Installation and Commissioning 3.5 C-PLUG (Configuration Plug) C-PLUG removable memory medium as an alternative to flash memory The IWLAN/PB Link PN IO has an internal flash memory for storing the project engineering data. As an option, the device can be operated with a C-PLUG (configuration plug) removable memory medium. The IWLAN/PB Link PN IO can be operated with or without a C-PLUG. The existing flash memory is then only used when no C-PLUG is inserted. If a C-PLUG is inserted, the project engineering data is always stored on it. This simplifies replacement of modules. By simply exchanging the C-PLUG, all the data can be transferred to the replacement module. Response to an unknown or invalid C PLUG If a C PLUG is inserted that does not have the correct format or valid data for the IWLAN/PB Link PN IO, the IWLAN/PB Link PN IO will not start up. Device status: System fault LED lit. To ensure that you can access the IWLAN/PB Link PN IO via the WLAN interface in this status, the WLAN parameters stored in the internal flash memory are used. If you know this parameter, please format the C PLUG with NCM diagnostics or replace the C PLUG with a C PLUG with valid data. If, however, you do not know this parameter and cannot establish a connection in the WLAN, use the RESET button to run a reset to factory settings with the C PLUG inserted (see Section 5.2); you then operate with the default WLAN parameters. Notice The C-PLUG may only be inserted or removed when the power is turned off! BL2 22

23 3 Installation and Commissioning Figure 3-2 Fitting a C-PLUG in the IWLAN/PB Link PN IO and Removing a C-PLUG from the IWLAN/PB Link PN IO using a Screwdriver Table 3-1 Working with and without a C-PLUG Progress / status Behavior during data transmission Result after startup Settings as shipped (after parameter assignment with PRESET PLUG or over Telnet/CLI) Operation without C PLUG C PLUG not inserted. The configuration data is transferred from the STEP 7 project. The following differentiation is made here: Use as Gateway only: Project engineering data transferred by the download function of STEP 7. Use as PROFINET IO device: Project engineering data transferred from PROFINET IO controller. The IWLAN/PB Link PN IO uses the configuration data transferred to the internal flash memory. 1) C PLUG inserted in the module with settings as shipped (after parameter assignment with the PRESET PLUG or over Telnet/CLI) BL2 23

24 3 Installation and Commissioning Table 3-1 Working with and without a C-PLUG, continued Progress / status Behavior during data transmission Result after startup Empty C PLUG is inserted. The configuration data is transferred from the STEP 7 project. The following differentiation is made here: Use as PROFINET IO device: Project engineering data transferred from PROFINET IO controller. Use as Gateway only: Project engineering data transferred by the download function of STEP 7. The IWLAN/PB Link PN IO uses the configuration data transferred automatically from the internal flash memory to the C PLUG. 1) C PLUG with configuration data is inserted. Requirement: Project engineering data must be valid for the IWLAN/PB Link PN IO 2) Result after startup: The IWLAN/PB Link PN IO starts up with the project engineering data stored on the C-PLUG. The IWLAN/PB Link PN IO uses the configuration data on the C PLUG. 1) In its configured state, the module is already equipped with the C PLUG. Empty C PLUG is inserted. C PLUG with the configuration data is inserted Requirement: Project engineering data must be valid for the IWLAN/PB Link PN IO 2) When the IWLAN/PB Link PN IO is started, the configuration data is loaded from the internal flash memory to the C PLUG. The configuration data is deleted from the internal flash memory. Provided that the C PLUG for the IWLAN/PB Link PN IO contains valid configuration data, this data is used. The data in the internal flash memory is ignored. During the next startup, the internal flash memory is reset. The internal WLAN parameters, however, are not deleted. The IWLAN/PB Link PN IO uses the configuration data transferred from the flash memory to the C PLUG. 1) Result: The IWLAN/PB Link PN IO starts up with the project engineering data stored on the C-PLUG. 1) 1) Note on use as a PROFINET IO device: Only the device name and the WLAN parameters are stored retentively on the C-PLUG; project engineering data is transferred by the PROFINET IO controller during each startup and stored in volatile memory. 2) Note: If the C-PLUG has no valid project engineering data for the IWLAN/PB Link PN IO, the device will not start up! In this case, use the NCM diagnostics to clarify the situation and, if necessary, format the C PLUG. BL2 24

25 4 Configuration with STEP 7 4 Configuration with STEP 7 To connect (initial addressing) and configure the IWLAN/PB Link PN IO, you need the STEP 7/ NCM S7 configuration software (as of version V5.3 SP2 Hotfix 1. Notice If the hardware catalog of HW Config in your STEP 7 installation does not contain the IWLAN/PB Link PN IO component, you have to also install the hardware update in STEP 7 / HW Config. The hardware update is on the CD supplied with the product and can be found in the directory: software/hsp_1009 In STEP 7 / HW Config, choose: Options Install Hardware Updates... For information on how to continue, see the online help in STEP 7. After installation and parameter assignment, the device can be configured and the configuration data downloaded in two different ways depending on the application: Initial situation: The device is commissioned at the WLAN end (see Section 3) and can now be supplied with configuration data. Subsequent procedure depending on application Configuration with STEP 7 for use as a PROFINET IO device and gateway > See Section 4.1 Configuration with STEP 7 for use as gateway only > See Section 4.2 The device is ready BL2 25

26 4 Configuration with STEP Use as a PROFINET IO Device and as a Gateway For this application, configure the IWLAN/PB Link PN IO as a PROFINET IO device with STEP 7/HW Config and assign a DP master system to the IWLAN/PB Link PN IO. Load the configuration data to the PROFINET IO controller, which then automatically loads it to the IWLAN/PB Link PN IO. Notice You must always restore the factory settings when you switch the configured IW- LAN/PB Link PN IO operating mode. The device can only be operated as a PRO- FINET IO device or as a gateway Configuring the Properties with STEP 7 To assign address information and further parameters to the IWLAN/PB Link PN IO, you have to generate a loadable database (configuration) in STEP 7. Follow the steps below Step Configuring the IWLAN/PB Link PN IO as a PROFINET IO device with STEP 7/HW Config 1. Use an existing STEP 7 project in which you have already created a PROFINET IO controller (e.g. an S7-400 station with a CP Advanced). 2. Open HW Config by double-clicking the station you created. 3. Take the device type gateway IWLAN/PB Link PN IO from the hardware catalog under PROFINET IO and add this as an IO device on the PN IO system of the IO controller. An IP address for the PROFINET IO system interface is determined automatically here. STEP 7 also assigns a device number to the IWLAN/PB Link PN IO. It chooses the highest free device number in the current PROFINET IO system. Step Connecting the PROFIBUS subnet in the STEP 7 project 4. Once you have transferred the IWLAN/PB Link PN IO from the hardware catalog, you are prompted to network the IWLAN/PB Link PN IO to the PROFIBUS interface. If you have not yet created the required subnets, you can do this now by selecting the relevant entry. This creates a DP master system. Results: In HWConfig, the IWLAN/PB Link PN IO is created as a PROFINET IO device with a DP master system. BL2 26

27 4 Configuration with STEP 7 Step Connecting the PROFIBUS subnet in the STEP 7 project 5. Set any other required properties of the IWLAN/PB Link PN IO (see also Section 4.3). 6. Configure the DP master system and its DP slaves. Note For the IWLAN/PB Link PN IO, the DP master system is assigned to the PROFIBUS submodule. If you want to create a new DP master system, therefore, you first have to choose the PROFIBUS submodule. BL2 27

28 4 Configuration with STEP Update Time for the PROFINET IO System You can display and set the parameters described below in the properties dialog box for the PROFINET IO system in HW Config. Setting the update time Update times can only be set in certain intervals. STEP 7 determines the relevant values on the basis of the properties of the IO devices involved. If you change the basic hardware configuration, for example, add new IO devices, the update time can change. The next time you open the dialog, a message informs you that the update time has changed. The default value for the update time is calculated automatically depending on the maximum number of links on an IWLAN segment (or AP). Notice Note that the update time you choose for the SCALANCE W788-RR must be identical to the setting described here for the IWLAN/PB Link PN IO in the STEP 7 configuration. Set the update time over the CLI in the following menu: ifeature ipcf PN IO Update Time BL2 28

29 4 Configuration with STEP 7 Selection of channels to be scanned The minimum selectable update time is decided by the number of WLAN clients on an access point in the configuration in STEP 7. To keep the proportion of cycle time required for scanning channels to a minimum when roaming, we recommend that you use the Background scan channels setting. This restricts the number of channels on which the IWLAN/PB Link PN IO scans for a channel. To use this, select the following settings in the Interfaces wlan1 Advanced menu: Background scan channel select > activates the background scan Background scan channels > selection of channels to be scanned This optimizes the roaming characteristics in terms of time. Optimizing the update time You can optimize the update time by specifying the maximum number of links in your system on the IWLAN Parameters tab. Notice If the update time you choose is too short or if the IWLAN segment has more links than you specified on the IWLAN Parameters tab, this may cause the connection to be interrupted. For this reason, you are advised to retain the default settings. When optimizing the update time, you must take into account the following points to ensure stable communication: Case a: your system is operated in a single wireless segment; in other words, the clients (IWLAN/PB links, SCALANCE W74x) do not need to support roaming to another wireless segment. In this case, update times of >=8 ms are supported. Optimum wireless conditions without roaming: update times of 4 ms are only possible under optimum wireless conditions and when the cell has just one client. Case b: your system is operated with two wireless segments on two different channels. In this case, update times of >=16 ms are also supported. Case c: your system is operated with more than one wireless segment and more than two channels. The clients also switch between the segments (roam). In this case, the PN IO update time should be higher than 16 ms. BL2 29

30 4 Configuration with STEP 7 Notice You are strongly advised to check the local radio conditions before commissioning. Note For a detailed description of the commands of the command line interface (CLI), see the operating instructions for the SCALANCE W744. These operating instructions (file name: MN_SCALANCE_W74X_0[76]) can be found on the CD supplied with the IWLAN/PB Link PN IO or on the Internet at the following address: BL2 30

31 4 Configuration with STEP Assigning Device Names and Downloading the Configuration The IWLAN/PB Link PN IO is supplied with a fixed MAC address. Without further configuration, the device can only be accessed over the WLAN port using this MAC address. An IP address is automatically assigned during configuration. Later when the PROFINET IO controller is started up, this IP address is transferred to the IWLAN/PB Link PN IO (IO device). To ensure that the IO controller can identify the IO device during this procedure, you first have to assign a device name to the IWLAN/PB Link PN IO as you do to every other IO device. You only have to assign the name once. Follow the steps below Step Procedure 1. Assign a device name to the IWLAN/PB Link PN IO (you only have to do this once). You can do this in the SIMATIC Manager or in HW Config with the menu command PLC Ethernet Assign device name... (More detailed information on this procedure is available in the STEP 7 online help.) 2. Load the configuration for the associated PROFINET IO controller. The IO controller receives the configuration data from the IWLAN/PB Link PN IO. When the IO controller is started up, the IWLAN/PB Link PN IO and all the other PROFINET IO devices are configured automatically. Note The configuration data loaded by the PROFINET IO controller is not stored retentively by the IWLAN/PB Link PN IO. When you switch the device off and then on again, all the configuration data except for the device name is deleted. During startup, the configuration data is reloaded by the PROFINET IO controller. BL2 31

32 4 Configuration with STEP Use As a Gateway Only For this application, configure the IWLAN/PB Link PN IO as an S7-300 station with STEP 7/HW Config and load the configuration data to the IWLAN/PB Link PN IO. Notice You must always restore the factory settings via NCM diagnosis (see Section 5.2.2) when you switch the configured IWLAN/PB Link PN IO operating mode. The device can only be operated as a PROFINET IO device or as a gateway Configuring the Properties with STEP 7 Follow the steps below Step Configuring the IWLAN/PB Link PN IO as an S7-300 station with STEP 7/HW Config 1. Use an existing STEP 7 project or create a new one. 2. Create a station of type SIMATIC Open HWConfig by double-clicking the station you created. 4. From the hardware catalog under SIMATIC 300 / gateway, choose the device type IWLAN/PB Link PN IO. BL2 32

33 4 Configuration with STEP 7 Step Connect the IWLAN/PB Link PN IO to the Ethernet and PROFIBUS subnet in the STEP 7 project 5. Once you have copied the IWLAN/PB Link PN IO from the hardware catalog, you are prompted to network the IWLAN/PB Link PN IO on the Ethernet interface and then on the PROFIBUS interface. If you have not yet created the required subnets, you can do this now by selecting the relevant entry. Result: You have created the IWLAN/PB Link PN IO component with a basic module and the Ethernet and PROFIBUS submodules in the S7-300 station in HW Config. 6. Set any other properties of the IWLAN/PB Link PN IO. For more information about this, see Sections to Assigning the IP Address and Loading the Configuration The IWLAN/PB Link PN IO is supplied with a fixed MAC address. Without further configuration, the device can only be accessed via the WLAN connection using this MAC address. Step Commissioning the IWLAN/PB Link PN IO 7. Assign an IP address to the IWLAN/PB Link PN IO provided you have not already done this in the SIMATIC Manager independently of the configuration steps described here. To do so, choose the following menu command in HW Config PLC Ethernet Assign Ethernet Address Load the database (configuration) from STEP 7 to the IWLAN/PB Link PN IO. The initial load process must be carried out from the Industrial Wireless LAN via the TCP/IP interface. Subsequent load processes can be carried out from PROFIBUS or the Industrial Wireless LAN via the TCP/IP interface depending on the PG connection. Notice Note that the IWLAN/PB Link PN IO is a special configuration component that already contains all the required station components. For this reason, you cannot place any other component (e.g. rack or modules) next to the IWLAN/PB Link PN IO. BL2 33

34 4 Configuration with STEP Parameters in the Properties Dialog Box for IWLAN/PB Link PN IO You can set the other IWLAN/PB Link PN IO properties in HWConfig or via the component view in NetPro (with gateway operation only). BL2 34
